Abstract
The utility model relates to a rolling rotor type air conditioning compressor with a Y-shaped oil sump; the compressor comprises an upper cylinder cover; the inner hole of the upper cylinder cover is provided with an oil sump; the oil sump comprises a single oil sump and at least two oil distributing sumps separated from the single oil sump; the position of the oil sump keeps off the stressed surface on which the upper cylinder cover and a crankshaft are adhered most tightly with largest pressure. The air conditioning compressor can effective increase the oil supply of the upper cylinder cover, reduce the wear of the upper cylinder cover and the crankshaft, improve the reliability of the compressor, prevent the increased input power and impact on the COP value of the compressor because of the wear of an upper bearing, and avoid the situation that after the crankshaft is worn, the crankshaft deforms or inclines, and electromagnetic sound is led to.
Description
Technical field
The utility model relates to a kind of rolling rotor-type air condition compressor with bifurcated oil groove, especially can improve the oil film that compressor upper cylinder cover inwall fuel feeding deficiency causes and forms deficiency and wear and tear unusual air condition compressor relevant for a kind of.
Background technique
With reference to shown in Figure 1, air condition compressor upper cylinder cover 9 constitutes the active chamber of rolling rotor type compressor with piston, blade, following cylinder cap (two (n) cylinder compressor comprises intermediate plate) (not shown) cylinder etc.; Upper and lower cylinder cap constitutes the spring bearing of crankshaft rotating together; Offer relief opening (also have at following cylinder cap and offer relief opening) at upper cylinder cover 9, realize the compressor air-discharging function; The rolling rotor type compressor pump housing and rotor portion fix by upper cylinder cover 9 (or cylinder) and housing welding.
Compressor upper cylinder cover 9 internal diameters and bent axle external diameter constitute sliding bearing; its endoporus and bent axle generation sliding friction; in order to reduce the abrasion between these two product and to improve bearing life; upper cylinder cover 9 internal diameters and bent axle external diameter need oil lubrication; specific practice is offered oil groove 91 in upper cylinder cover 9 inner diameter wall; Oil Guide path of processing on specific practice upper cylinder cover 9 inner diameter wall; make lubricant oil to be lubricated cylinder cap internal diameter and bent axle surface along this path; and formation one deck oil film; avoid upper cylinder cover 9 directly to contact the generation dry friction with bent axle; thereby protection upper cylinder cover 9 and bent axle also reduces frictional loss, improves compressor efficiency.
In the prior art, rolling rotor type compressor upper cylinder cover 9 oil grooves 91 are single spiral half slot, extend to the cylinder cap upper-end surface from the cylinder cap base plane.But make that the oil groove degree of depth and groove width all can not be excessive owing to be subjected to the restriction of upper cylinder cover 9 other structures (annular groove), otherwise will influence cylinder cap intensity.
In these prior aries, upper cylinder cover 9 oil grooves 91 are the half slot of single-screw shape, and carrying out can taking place in the test of compressor related reliability upper cylinder cover 9 at compressor has inordinate wear with the bent axle surface of contact.Find that by test and calculating the main cause of these wearing and tearing is that upper cylinder cover 9 inwall oil films form deficiency and oil groove is jagged and causes.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of rolling rotor-type air condition compressor with bifurcated oil groove, it can increase the fuel delivery in the cylinder cap internal diameter, for forming, oil film provides enough machine oil, guarantee the lubricated of upper bearing (metal) internal diameter and bent axle external diameter, reduce mechanical wear, avoid the fuel feeding deficiency, improve the reliability and the efficient of compressor.
Another technical problem to be solved in the utility model provides a kind of rolling rotor-type air condition compressor with bifurcated oil groove, and it can increase the oil groove degree of depth and groove width when not influencing cylinder cap intensity.
Another technical problem to be solved in the utility model provides a kind of rolling rotor-type air condition compressor with bifurcated oil groove, and it can reduce burr and have possibility, has reduced the inordinate wear of bent axle and cylinder cap.Meanwhile also make the oil groove groove width increase, improved the utilization rate of refrigerator oil in bearing portion.
In order to solve the problems of the technologies described above, the technological scheme that the utility model adopted provides a kind of rolling rotor-type air condition compressor with bifurcated oil groove, it includes a upper cylinder cover, offer oil groove in the endoporus of upper cylinder cover, at least 2 the branch oil groove that this oil groove includes a single oil groove and told by this list oil groove; Oil groove is offered the pressure maximum combined compression face the most closely of avoiding upper cylinder cover and bent axle in the position.
The utility model the beneficial effect that can bring be the fuel delivery that can effectively strengthen upper cylinder cover, reduce the wearing and tearing of upper cylinder cover and bent axle, the raising compressor reliability; And prevent to influence the COP value of compressor because the wearing and tearing of upper bearing (metal) increase input power; Can also avoid bent axle abrasion back crankshaft deformation or inclination might cause the generation of electromagnetism sound.

Embodiment
As Fig. 7 to Figure 12 shows that a kind of preferred embodiment of the utility model with rolling rotor-type air condition compressor of bifurcated oil groove.This compressor includes a upper cylinder cover 1, offers an oil groove 11 in upper cylinder cover 1 endoporus, and this oil groove 11 comprises that at least 2 equidirectional spirals in the lower end surface divide oil groove 12, merges into 1 single oil groove 13 in the process that 12 rotations of minute oil groove are risen.
Among another embodiment of the utility model, offer an oil groove in the upper cylinder cover endoporus of compressor, this oil groove comprises a single oil groove in the lower end surface, is divided at least two branch oil grooves in the process that single oil groove rotation is risen.
The pressure maximum combined that oil groove 11 need be avoided upper cylinder cover 1 and bent axle is compression face 14 the most closely.After once milling out oil groove 11, can also append and carry out notch and mill chamfering 15 this oil groove 11.
